Thank you Marylin, I saw it also first time, I just do not know what exactly the crab is doing with the Clown fish eggs? ( I think they are the clown fish eggs??? ). Does he eat it? In the picture it looks more like guarding :-)) Maybe somebody has detailed knowledge???

"Reproduction Porcelain crabs are often found in heterosexual pairs. They have internal fertilization, the male passing sperm to the female in the form of a tiny packet called a spermatophore. The eggs are carried by the female in a brood flap, on the abdomen. A single female may carry nearly 1,600 eggs at a time. The larvae are planktonic for several weeks before settling."
